RAILWAY-RAIL.

Patented Apr. 21, 1914.

Application filed January 4, 1913, Serial No. 740,233. Renewed September 17, 1913. Serial No. 790,377.

To all whom it may concern:

Be it known that I, ALFRED H. MOORE, a citizen of the United States, residing at New York, in the county of New York and State of New York, have invented certain new and useful Improvements in Railway-Rails; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters and figures of reference marked thereon, which form a part of this specification.

This invention relates to new and useful improvements in railway rails, the object in view being to produce a rail which will have a much greater tensile strength, affording a greater safety factor than with the usual rails now employed and thereby afiording a longer wearing life to the rail.

The invention consists further in the provision of a rail of combination steel and iron, the combination being effected in a non-oxidizing atmosphere and consisting in a fusion of the metals, first forming an ingot with steel center and best iron envelop and afterward cutting the ingot in order to expose a steel surface which, when rolled, will form the tread or crown surface of the rail, while the best iron will form a continuous chair for the web and flange of the rail.

My invention is illustrated in the accompanying drawings, in which Figure 1 is a perspective view of an ingot having an inner core of steel and an envelop of best iron fused thereto, a portion of the ingot being shown in section. Fig. 2 is a detail view showing the ingot in section, and Fig. 3 is a perspective view of a rail rolled from one of the sections shown in Fig. 2 and having a tread surface of steel and a continuous chair and flange of best iron and fused to the steel core.

In making the rails in accordance with my invention, an ingot, previously prepared with an inner core of steel with a uniform percentage of carbon as may be desired to meet different conditions, is provided with an outer envelop of best iron fused thereto which is utilized by first cutting the ingot to expose a steel surface which, when the ingot is rolled into a rail, will form the crown or .tread surface thereof. It will be understood that the original preparation of the ingot and its being cut and formed into a rail are done in the same heating. In heating the ingot, the envelop of best iron must be brought to a white heat and at which stage the steel forming the center will be in a semi-liquid or half molten condition. In this condition, the steel throws oif carbon which consumes or destroys any of the phosphorus or sulfur contained in the iron, resulting in the production of an ingot equal and superior to the best charcoal iron with an appreciable gain in tensile strength. The ingot is then passed through the rolls with a gentle pressure so as not to burst the envelop and thereby cure the steel of porosity. In the treatment of the ingot, the welding temperature of the iron should be such as to show a white or welding heat and the inclosed steel should be in a molten state in which condition, if brought under gentle pressure, it will be cured of porosity, it being understood that the wrought iron at 2700 degrees F. will stand a considerable pressure upon the inside and will hold the molten or half molten steel safely if too great pressure is not brought to bear upon it. When the material of the ingot is in proper condition, it is split and the section of the ingot rolled by any suitable rolling mechanism in such a way that the split surface will form the tread or crown of the rail while the best iron, which is fused to the steel core, will form a continuous chair or envelop for the web and flange of the rail.

A rail made in accordance with my invention will have a hard tread surface of greater tensile strength and will have a longer wearing life than will rails commonly in use iron having a steel core and forming a con- 10 where the entlre rail 1s made of steel or of tlnuous support.
